Near-field earthquake ground motions may contain distinctive coherent velocity pulses. Strong with such large pulses can be damaging to structures located within the near-field region. A class of semiactive control algorithms referred as active interaction (AIC) have been developed a means suppressing vibration building during moderate earthquakes. Modal response-based AIC approaches shown effective in vibrations subjected far-field previous studies. Unlike resonant modelike response more...
To investigate the seismic behaviors of novel steel-reinforced concrete composite frames prestressed with bonding tendons (PSRCFs), 15 groups PSRCF specimens were designed following main parameters: cubic compressive strength high-strength (fcu), axial compression ratio frame columns (n), slenderness (β), steel angle (α), span–height beams (L/hb), and prestressing degree (λ). Based on modified constitutive model proposed by Mander effect applied cooling method, finite element models PSRCFs...
The effects of recycled powder (RP) on hydration, micro-structures, compressive strength and tensile properties high-ductility cementitious composites (HDCC) were studied. Three mass ratios RP ranging from 10, 30 to 60% employed partially replace the cement. hydration kinetics RP-amended matrix was measured investigate influence process phase development quantified by thermal gravimetric analysis. Mechanical properties, including HDCCs obtained at 28 days. morphology reinforced polyethylene...
Abstract In this paper, the performance of active interaction control (AIC) algorithms is assessed within context two realistic building models. The AIC approach proposed as a semi‐active means mitigating structural response during large earthquakes. To implement into MDOF systems, modal (MC) that directs effort to certain dominant modes formulated and utilized herein. Two structures, 3‐storey 9‐storey steel‐framed benchmark controlled by are analysed for historical earthquake records....
This article presents a general framework for sensor-driven structural health prognosis and its application to probabilistic maintenance scheduling. Continuously collected sensor data is used update the parameters of stochastic degradation model. Uncertainty in (i.e. measurement error) explicitly modelled as an evolving process. The proposed utilises Bayesian theorem Markov Chain Monte Carlo (MCMC) sampling calculate posterior distributions updating allows use dynamic diagnostic information...
Abstract This paper presents a statistical performance analysis of semi‐active structural control system for suppressing the vibration response building structures during strong seismic events. The proposed mass damper device consists high‐frequency with large stiffness, and an actively controlled interaction element that connects to structure. Through modulating operating states elements according pre‐specified logic, vibrational energy in structure is dissipated thus suppressed....
Abstract This paper presents a family of semi‐active control algorithms termed as active interaction (AIC) used for seismic response civil structures. AIC include interface damping (AID), optimal connection strategy (OCS) and tuned (TID). A typical SDOF system consists primary structure, an auxiliary structure element. The typically has stiffness comparable to that the while its natural frequency is much higher than structure. Interactions between structures are defined by specific logic...
In this paper, a numerical simulation study was conducted on the seismic behavior and ductility demand of single-degree-of-freedom (SDOF) systems with partially self-centering hysteresis. Unlike fully systems, display noticeable residual displacement after unloading is completed. Such has been observed in number recently researched structural energy dissipation devices. It thus interest to examine performance such as systems. study, modified flag-shaped hysteresis model proposed represent...
This article presents an overview of smart structures technologies in connection with long-span cable-supported bridges. Considering the broad scope technologies, two subareas, namely, structural health monitoring and control their applications cable supported bridges, are identified as focus this review. It is believed that by, adopting reliable operation hazard management bridges can be achieved much more efficiently made economically feasible, especially for located at sites high risks...
